出现这个问题的原因大部分是忘记添加如下的maven依赖，

        < dependency>
		    <groupId>org.yaml</groupId>
			<artifactId>snakeyaml</artifactId>
			<version>1.25</version>
		</dependency>

当然，我添加了依赖，但却还是报这个错，找了好久也没找到问题所在，最后在一位大佬的指点下找到了问题所在，是由于父项目和子项目的snakeyaml版本与项目的版本不一致导致的。如何查找项目的版本呢？我的错误是java.lang.NoSuchMethodError: org.yaml.snakeyaml.LoaderOptions.setMaxAliasesForCollections(I)V这个，我就首先想到了用全局查找找一下我的项目中setMaxAliasesForCollections的版本等一些方面（我用的是IDEA，全局查找的方式是Ctrl+N，eclipse的话应该是Ctrl+H，别的编辑器就不太清楚了，可以自行BD一下），如图所示：

ps：请注意，上图有5个范围，最好是都查找一下，防止遗漏！！！
我检查了自己的版本，是1.25，和这个的版本不一致，因此导致了上述的错误，改一下版本就好了！
